On a very hot summer night in NYC, I opened the freezer door of a friend of mine to see a box of butter taking up room on the door shelf. On one hand, it made sense – if you go for several weeks between uses, keeping it frozen seems like the sensible thing to do. But isn’t butter (for the most part) dairy?

Yuck.

Cannabinoids and terpenes naturally degrade over time, but proper storage can elongate their life and keep them efficacious for longer. Even when freezing, cannabis products need to be kept in cool, dark, and dry places in airtight containers. Think mason jars, but any repurposed jar that can be sealed tight will do. Stored properly, cannabutter can last up to six months in the freezer, but its quality and taste will be better and more potent if you use it before then.

How Do You Store Cannabutter?

If you’ve made your own, you may be tempted to take your creation and stash it right away in the freezer, but be patient.

Here’s a fun and creative alternative to the glass jar storage: if you have a BPA-free silicone ice cube tray, let the cannabutter freeze in the tray overnight, then wrap the cubes in wax paper and store in an airtight freezer or Ziploc bag. This is a super convenient method if you’d like to spread it on toast or add a couple of tablespoons to a recipe like pancakes, for example.

How Do You Unfreeze/Thaw Cannabutter?

There are a couple of ways to thaw cannabutter, and both of them are super easy. One method is to transfer it from the freezer to the refrigerator overnight. If you need it sooner, you can submerge it in its storage container in a bowl of warm water for 30 minutes or so.

Before jumping into thawing, you’ll want to consider how much you’ll need. If you thaw, then refreeze any kind of butter, its taste will definitely be affected, so plan ahead so you don’t waste it.
